The Adjustable Span Kit allows for easy crane width adjustments without drilling the I-beam.
The Wallace Adjust-A-Span kit is optional and available for Thrifty cranes with I-beam lengths of 15′ or less.
All adjustments of several feet to fractions of an inch are made by sliding the entire frame and post assembly on the I-beam. Set screws in the bracket hold the I-Beam in place.
Kit includes 2 sets of I-beam brackets and mounting hardware.
